Disclosed are an invasive needle which emits light through an optical fiber inserted into a puncture needle, and a manufacturing method thereof. The invasive needle includes an optical fiber and a puncture needle including the optical fiber therein, and the puncture needle includes an opening to emit light at an end of the optical fiber. Therefore, by inserting the optical fiber inclined at various angles into the puncture needle, which is used for medical purposes, the light is emitted from the side to invade acupuncture points during acupuncture treatment, and the light spreads widely, thereby maximizing the acupuncture treatment effect.n n n n Invasive, needle, puncture, optical fiber, manufacturing method |
